FLASH-LIGHT.

To all whom it may concern:

Be it known that I, HYMAN BIEBER, a subject of the King of England,residing at 54 Islington, Liverpool, in the county of Lancaster,England, haveinvented certain new and useful Improvements in or Relatingto Flash-Lights, of which the following is a specification.

This invention relates to electric flash lights, and has for its objectto provide a lamp construction which shall be simple, cheap andeflicient, and wherein a dry cell of common type may be employed.

I will describe my invention with the aid of the accompanying sheets ofexplanatory drawings, in which Figure 1 represents the lamp inlongitudinal section.

Figs. 2 to 5 illustrate a preferred construction of sheath or casinghereinafterdescribed.

Referring first to Fig. 1, a generally designates a one-piece sheath orcasing having open ends and which is constructed of stiff paper orcardboard on which is pasted or suitably secured a paper covering b thatcloses the outer end of the sheath or casing, except for a smallaperture d. The

paper covering has its inner end open and it is preferable to inturn theedges of said paper covering and secure the same to the inner wall ofthe sheath or casing.

Projecting through an aperture d in the casing top is the bulb e of anelectric filament lamp, said lamp having a base or the usual screwsocket 7 held by a sheet metal contact piece 9, say of tin plate.

' On said metal plate 9 is disposed a piec of stiff. paper or cardboard71/ k the sides h whereof are inturned; and extending from the casingtop are tongue pieces i which are doubled as shown. Said piece of paperor cardboard h k and side tongues constitute distance pieces or spacingmeans to. control the amount of projection of the lamp bulb 6 throughaperture d of the casing top.

9', 74, indicate the cell terminals, terminal 7' being a resilientmember. as-a spring plate or strip which maintains continuous contact 1with the insulated lamp terminal or socket,

and terminal in is a short vertical arm extending. toward the metalliccontact piece g.

When the cell 0 is shifted within the easing by applying'pressu're tothe lower end of the cell, the terminal Z: contacts with thecontactpiece g and closes the lamp circuit,

sheath or casing illustrated in Figs. 2 to 5,

wherein Figs. 2 and 3 are sections taken at right angles to each other,Fig. 4 a plan, and Fig. 5 a view of the casing blank; said casingembodies a portion Z adapted to form front, sides, and rear overlappingmembers,

a portion m adapted to form the casing' top and the distance pieces 2'hereinbefore referred to, and an inner depending member n designed tostiffen the casing structure.

0, Fig. 3, indicates a spring clip adapted to normally prevent the cellfrom sliding out of the casing.

Having nowdescribed my invention, what I claim as new and desire tosecure by Letters Patent is i 1. An electric flash light comprising acasing, an electric filament lamp, the bulb whereof projects through anaperture in said casing top, a metal plate secured in contact with saidlamp, means controlling the amount of projection of said lamp bulbthrough said casing aperture, and a dry cell' provided with a springterminal in continuous contact with said lamp and a terminal adapted tomake contact with said metal plate when said cell is moved within thecasing. I I 2. An electric flashlight comprising a'onepiece casingconstructed of stiff paper, an

.' electric filament lamp the bulb whereof pro jects through an aperturein said casing top, a metal plate secured in contact with tilemetallicsocket of said lamp, means dispos d between said metal plate andeasing top coiltrolling the amount of projection of said lamp bulbthrough said casing aperture, and a dry cell provided with a terminal incontinuous contact with said lamp, and a terminal adapted to makecontact with said metal plate, When said cell is moved Within thecasing.

In testimony whereof I affix my signature in the presence of twoWitnesses.

HYMAN BIEBER.
